2 vessels most commonly used in CABG

Saphenous vein and internal mammary artery

32

ST elevation in V2-V4 indicates which artery is occluded?

LAD. Anterior area of infarct.

33

ST elevation in V1-V3 indicates which artery is occluded?

LAD. Septal area of infarct.

34

ST elevation in II, III, and aVF indicates which artery is occluded?

either posterior descending or marginal branch. Inferior area of infarct.

35

ST elevation in I, aVL, V4-V6 indicates which artery is occluded?

LAD or circumflex. Lateral area of infarct.

36

ST elevation in V1 and V2 indicates which artery is occluded?

PDA. Posterior area of infarct.

37

Greatest risk of sudden cardiac death is how long post-MI?

First few hours from tach, fib, or cariogenic shock.

38

Which types of heart block get ventricular pacemaker?

Mobitz II or complete/third-degree block

39

PDA supplies?

Inferior wall of LV, posterior 1/3 of IV septum

40

Marginal branch supplies?

RA, RV

41

CO increases during exercise initially due to? Later due to?

Increasing SV, THEN increasing HR.

42

Vitamins that apparently help prevent CAD

Vitamins E and C as well as beta carotene

43

2 vessels most commonly used in CABG

Saphenous vein and internal mammary artery

44

Greatest risk of ventricular wall rupture is how many days post-MI?

4-8 days.

45

PR interval in first degree heart block

>0.2 sec

46

Second degree heart block Type I is caused by?

InTRAnodal or His bundle conduction defect, , drug effects (.eg., B-blockers, digoxin, CCB) or increased vagal tone.

47

Second degree heart block Type II is caused by?

InFRAnodal conduction problem (bundle of His, parking fibers).

48

Which types of heart block get ventricular pacemaker?

Mobitz II or complete/third-degree block

49

Narrow QRS not associated with p waves, rate of 60

3rd degree block (junctional rhythm)

50

Wide QRS not associated with p waves, rate >40 but

accelerated ventricular rhythm

51

Narrow QRS not associated with p waves, rate >100

junctional tachycardia

52

Wide QRS, not associated with p waves, rate 20-40

ventricular rhythm

53

Wide QRS, not associated with p waves, rate >100

ventricular tachycardia

54

Narrow QRS not associated with p waves, rate >60 but

accelerated junctional rhythm

55

Difference between wandering pacemaker and Multifocal atrial tacky?

>3 diff p wave morphologies but wandering pacemaker is ventric rate of 100.

56

Treatment for PACs?

None

57

Drug of choice in PSVT?

IV adenosine

58

Scenarios you'd see Kussmaul's sign

Increased JVD with inspiration is seen in right ventricular infarct, massive PE, constrictive pericarditis, restrictive cardiomyopathy, and rarely, cardiac tamponade.

59

When might a subclinical mitral stenosis from rheumatic heart disease become clinically apparent?

Volume overload state, such as pregnancy.

60

Diastolic murmur heard best in left lower sternum that increases with inspiration

Tricuspid stenosis
